I have an app with multiple buttons and text lines, I want to change the text depending on the language set in a menu. Ideally I want all the changes within a function to make the code easier, but the code does not work. I am not sure even if the function is been called, how do I change the text within the function when trigged by the button?
MainActivity.kt
MainActivity.xml
MainActivity.kt
Code:
package com.example.sandpit9
import android.content.Intent
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
imageButton1.setOnClickListener{toast(R.)}
imageButton1.setOnClickListener{
imageButton1.setImageResource(R.drawable.greenbutton)
textView1.setText("test 1")
}
}
private fun toast() {
val text: Any = textView2
textView2.setText("test 2")
}
}
